I know why, and I am perfectly fine with that, but is there any way I can up this limit? I have tried messing around with the "MTA Trusted Networks:" setting but have yet to find the right one. What should this be listed at to allow unlimited connections from my forwarding mail server?

Or alternately, what can I do to bump this threshold up? Like to 1000?

Thanks,

Bump

Anybody?

This causes a lot of backup on my primary mail server currently (since we are still working on migrating our zm users just have a .forward on the primary)

try

Code:

su - zimbra -c zmprov mcf zimbraLmtpNumThreads "250"

Note that 250 can be any number of smtp connections you need.

I have the same error
Connection concurrency limit exceeded: 51 from relay.domain.tdl [10.99.50.5] for service smtp : 4 Time(s)

Is 51 an error number or the number of concurrent connections?

I checked my current setting before changing and got an un-expected answer
